GO8 overview

Learn how GO8 tracks trips, alerts drivers, and checks engine health.

The GO8 is discontinued.

The GO8 is a compact telematics device. Like the GO7, it supports GPS tracking, g-force monitoring, IOX expandability, and engine and battery health assessments. It also communicates on the LTE network.


Two GO8 devices display the device housing and indicator lights.

Vehicle tracking

Geotab's patented tracking algorithm recreates vehicle trips and analyzes incidents. The GO8 provides in-vehicle alerts to immediately notify drivers of infractions. With hardware Add-Ons, it can also provide live coaching on driving performance.

Installation does not require a dash-mounted antenna or wire splicing.

Security

Geotab platform security is designed for end-to-end data protection. Key implementations include the following:

  • GO device and network interfaces use authentication, encryption, and message integrity verification.

  • Each device uses a unique ID and a non-static security key, making it difficult to fake the device's identity.

  • Over-the-air (OTA) updates use digitally signed firmware to verify that updates come from a trusted source.

  • Geotab uses independent third-party experts to validate the platform from end to end.

  • Federal Information Processing Standards (FIPS) 140-2 validation by the National Institute of Standards and Technology (NIST) (certificate #3371).
